  • the purpose of the present invention patent application is to register a brake system with multiple discs for vehicles that incorporates notable innovations and advantages over other known systems.

  • It is therefore an object of the invention to provide a brake system with multiple discs for vehicles comprising two or more brake discs arranged in a sandwich type configuration and on the same transverse central axis and braking means, characterized by the fact that said brake discs they are freely coupled (that is, each of the brake discs can have a slight axial displacement in order to have a self-centering device with respect to the faces of the brake pads located in an inner part) and separated a distance independently of each other on a hub that crosses the central hole of the disc brakes, each of said discs being provided with fastening means and guiding means with respect to the hub capable of allowing the free displacement of the disk of brake through the bushing independently.
  • the brake discs are identical to each other because they are mounted independently of each other and are both coupled on the hub and not one on the other as in the systems known in the known art.
  • the braking means consist of a caliper that has brake pads that come into contact with the two opposite faces of each of the discs, said caliper additionally having a support element housed in the existing space. between two brake discs, thereby multiplying the braking force by the number of discs for the same hydraulic pressure.
  • the guiding means consist of a plurality of bolts housed in cavities arranged radially on the outer side face of the bushing and housed in grooves arranged in the central part of the brake discs.
  • the system is provided with ventilation means housed in the space between two brake discs, which may consist of an air turbine capable of injecting fresh air at the high friction points, as well as on the outer walls of the own discs, since these only have to be mechanically designed to support the natural braking forces and not others as conductive or driven nor as a heat accumulator since this is dissipated by this effect almost instantaneously, thus reducing the thicknesses and the necessary material on the disc itself.

Abstract

L'invention concerne un système de frein à plusieurs disques pour véhicules, comprenant au moins deux disques de frein (1, 2) disposés selon une configuration de type sandwich sur un même axe central transversal, ainsi que des moyens de freinage. Les disques de frein (1, 2) sont disposés librement sur un moyeu (3) qui traverse l'orifice central des disques de frein (1, 2) et séparés d'une distance prédéterminée. Chacun desdits disques (1, 2) est pourvu de moyens de fixation et de moyens de guidage par rapport au moyeu (3), pouvant permettre le déplacement axial et libre d'un des disques de frein (1, 2) sur le moyeu, indépendamment de l'autre disque.
